Serial No. 558,106.

To all whom it may concern:

Be it known that I, FRED LATULIP, a citizen of the United States, and resident of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Machines for Molding Concrete Shingles, of which the following taken in connection with the accompanying drawings, is a full, clear, and exact description. I

My invention relates to the manufacture of composite shingles and more particularly to the type of shingle shown and described in my U. S. Letters Patent No. 907 ,824 issued on the 29th day of December, 1908, the object of this invention being to produce a simple, inexpensive and eflicient machine for molding such shingle.

To that end the invention consists in the novel construction and arrangement of the component parts of the machine hereinafter fully described and set forth in the claims.

In the accompanying drawings Figure 1 is a side elevation of the machine embodying my present invention; Fig. 2 is a front view of the same; Fig. 3 is an enlarged vertical longitudinal section of the upper portion of the machine; Fig. 4 is an enlarged plan view of the machine, the bed-plate upon which the concrete shingle is molded having been removed; Fig. 5 is a transverse section on the line X-X- in Fig. 3; Fig. 6 is a horizontal section on the line -YY- in Fig. 3; Fig. 7 is a detail transverse section of the rear end portion of the bed-plate; Fig. 8 is a side view of the shingle molded by the machine; and Fig. 9 is a back view of the shingle.

Like characters of reference indicate like parts in the several views of the drawings.

My molding-machine comprises essentially a horizontally disposed box lmounted upon a suitable frame 2 which may be of any desired construction. This box is of rectangular shape and is preferably composed of cast-metal and has its front end wall l hinged at its lower portion to the side walls for the purpose hereinafter explained. This front end-wall has pivoted to it a lever 3 adapted to engage a vertical slot 4 in one of the side walls to lock the said end wall in vertical position as more clearly illustrated in Figs. 3 and 4. WVithin this box is provided a bed-plate -5 which is preferably composed of cast metal and upon which the concrete shingle is formed. This bed-plate is supported removably upon vertical pins -66 fastened to the bottom of the box and said pins consist preferably of bolts secured into the bottom of the box and provided with nuts 7-7--. The purpose of employing the bolts is to permit the bed-plate to be adjusted vertically in order to increase or decrease the thickness of the shingle to be molded thereupon.

My patented shingle -A which is represented in Figs. 8 and 9 and which is pro duced by this machine has its back formed with a hook a extending across the upper end thereof for hanging it on a purlin and a similar locking-hook -bin proximity to the lower end of the shingle, and an undercut groove c across the front of the shingle for receiving the locking-hook of the correspondingly formed overlying shingle. To produce the hook a of the shin gle the aforesaid bed-plate is formed at its rear end with a depression -8 which becomes filled with the concrete deposited upon the said plate. Said depressed portion is open at its rear side to accommodate an obliquely disposed elongated core-plate 9 which is longitudinally movable and has its upper edge beveled and normally flush with the correspondingly inclined upper face of the rear end portion of the bed-plate as clearly shown in Fig. 3. This core-plate serves to produce the undercut on the hook formed in the said depression. The said core-plate 9- has its longitudinal edges fitted in guides -1010 formed on two oppositely disposed vertical plates -1l11-- depending from the bottom. of the box 1-, and the said core-plate is retained in said guides by means of metalstrips --12-12 secured onto the edges of the plates 11-11- and bearing against the core-plate as shown more clearly in Fi 6.

The core-plate has attached to it one end of a spiral-spring 13 by means of a hook-shaped member 14 secured onto the plate, the opposite end of which spring is connected to a similar hook-shaped member --15 secured onto the bottom of the box as clearly shown in Fig. 3. This spring serves to draw the core-plate upwardly to retain the same in the required position during the operation of molding. The lower tened thereto by means of bolts -2121.

The opposite end of the lever 18 is pivotally connected to the lower end of a vertical bar 22- by means of a bolt -23, the upper end of which bar is rigidly fas tened to the underside of an elongated plate 24.- disposed flatwise below the bottom of the box -1. This plate 2l is fastened to the upper portion of a vertically disposed rod 25 which is designed to be lifted. To connect the plate 24.- to the rod 25, I circumferentially reduce the upper end portion of the rod so as to provide a shoulder -26 upon which the plate is seated, and at the same time produce a post 27 extending through the bottom of the box 1, through which reduced portion and a boss on the plate passes a transverse pin 28. Extending upwardly from the end portions of the plate *-24 are additional posts -2727 -27 corresponding in length to the post 27- and extending through the botom of the box 1-. The posts 27 27 may be attached to the plate 24 in any suitable manner, however for convenience I circumferentially reduce the end portions of the said posts and insert the same in apertures 2929, through which reduced portions and plate extend pins 3030- as clearly represented in Fig. 3 of the drawings. The posts -2727 27 are normally out of contact with the bed-plate -5 and they serve to elevate the said plate for the purpose of removing the latter when the molding operation is completed which will be shortly explained.

The rod 25 has its lower end portion passing through a suitable guide 31 formed on the upper end of a post 32 which is fastened to the bottom of the frame 2 by means of bolts 33-33, to which post is pivotally connected a footlever 34eas indicated at -35. Said foot lever serves to lift the rod 25 and may be attached thereto in any convenient manner. In the present instance I show the said foot-lever connected to the said red by an auxiliary rod -36 which ispivotally connected at one end to the lever asv indicated at 87- and pivotally connected at its opposite endto a collar -38 on the rod as indicated at 39-, said collar being fastened to the rod 25 by means of a transverse pin -4=0- passing through the parts as clearly illustrated in Figs. 1 and 2.

In order to form the undercut groove c across the shingle, I provide a cor-- respondingly shaped core-plate Ll ex-v tending across the top of the box at the rear end thereof. This core-plate is supported at its ends removably on opposite sides of a rectangular frame 42- which is pivoted at'its rear end to the corresponding endwall of the box l. To effect the attachment of the said frame -42- I form the rear-wall of the box with two oppositely disposed perforated ears 43-43-' and provide the side members of the said frame with coinciding apertures through which aperturespass bolts a4.-et-. This frame is adapted to rest upon the side walls of the box -1 and by pivoting the same as shown it may be thrown u owardly as is required for the purpose 0 removing the bed-plate from the box .and replacing it therein. The aforesaid core-plate 4:1- is preferably seated in correspondingly shaped recesses -41 -4@1 in the side members of the frame -42.

The front end of the frame 42 has atdisposed a removable transverse core-plate ;4c7 as clearly illustrated in Fig. 3. The rear edge of this core-plate is beveled correspondingly with the front edge of the aforesaid core-plate -4t1 so that the locking-hook thus formed will fit the undercut of the groove produced by the plate 4L1 In the operation of the machine the frame t2 is swung upward,. and after placing gthe bed-plate 5 in the box 1- the core-plate l7- is placed upon the said plate so as to abut against the front wall of the box. The concrete or other plastic composition is deposited in the box in sufiicient quantity to fill the box with exception of a small portion of its rear end. WVhen the box gis thus filled a smoothing-plate -48 is idrawn forwardly along the top of the box face of the shingle.

1- for finishing the upper or front sur- This smoothing-plate 1 is preferably provided on its under side with a series of ribs 4E9-t9 for the purpose of forming longitudinal grooves in the said surface. Thls smoothing-bar 1s formed on its under side with two perforated lugs 5050- disposed at opposite end portions thereof and through said lugs pass parallel rods 5151 which are pivoted at their rear ends by means of bolts 5252 to perforated ears -5353 formed on the rear end of the box, said rods serving as guides for the said lugs incident to the movement of the bar. By pivoting the said rods as described the smoothing-bar may be swung up out of the way. After this smoothing-bar has been manipulated, the operator deposits an additional amount of the concrete into the box so as to completely fill the rear end portion thereof, whereupon the aforesaid frame l2- is swung downward and then the core-plate -4lis set in the recesses -41 in the side members of the frame whereby the said core-plate is caused to form the undercut groove in the front of the shingle. A trowel or other implement may be then used to remove the superfluous amount of concrete which may be above the frame so as to produce a surface which is flush with the said frame. Following this operation the attendant removes the coreplate 41- and swings the frame 42- upward as before stated in which position it may be retained by any suitable means. It will also be understood that any convenient device may be employed for retaining the smoothing bar in its raised position. It is obvious that by packing the concrete firmly in the rear end portion of the box, the aforesaid depression or recess 8 in the corresponding end portion of the bedplate will become filled with the concrete so as to form the hook on the back of the shingle a as represented in Figs. 8 and 9, and at the same time the inclined plate 9- disposed at the rear side of the depression will produce the undercut surface of the hook. It will be understood that the bottom side of the transverse member of the frame -42 is shaped to conform to the groove formed in the upper or front surface of the shingle which was produced by the aforesaid smoothing-bar 4t8. When the shingle is thus molded the frame 42 is swung upward out of the way and the lever 3- is lifted from the slot 1 in the side wall of the box so as to unlock the front wall -1* to allow the latter to be swung forwardly. The operator now depresses the foot-lever 34lwhereby the rod 25 is caused to lift the plate -24. By this movement of the plate 24. the lever 18 draws the core-plate 9 downward so as to clear the depression -8 of the bed-plate, and at the same time the posts 27-27*-27"- are caused to come in contact with the bottom of the bed-plate so as to lift the latter and thus allow the bedplate to be readily removed from the box. It will be understood that when the bedplate is thus removed it is to be placed in any -suitable locality to allow the molded shingle to become firmly hardened. Upon removing the bed-plate, the operator releases the foot-lever whereupon the spiralspring 13- draws the core-plate 9 up to its normal position and at the same time causes the plate 24 to be lowered to its normal position.

I prefer to provide the bottom of the box -l with openings in order to allow the box to be readily cleaned as required.

What I claim is 1. In a machine for molding composite shingles of the type specified, the eombination of a suitably supported horizontally disposed box, a bed-plate disposed removably in said box, means su ported below the box for lifting said bee-plate, an inclined sliding core-plate supported on the box and drawn downward by the said lifting-means, means automatically drawing said core-plate upward, and a manually operated lever for actuating said liftingmeans as set forth.
